A shroud (86) encompasses the secondary fan (82) to substantially block air pushed through the heat exchanger (40) by the primary fan (50) from the secondary fan (82).
A coaxial jet fan system has a primary fan, a flow control element to reduce swirl, and a secondary fan, mounted in a series configuration.
The secondary fan (82) also substantially eliminates the recirculation of air back through the heat exchanger (40).
The secondary fan may have the same or a lesser number of blades as the fan and the pitch of these blades can be such as to provide the required output.
The secondary fan (82) is rotatably mounted in a substantially concentric relation with the primary fan (50) to pull air through the heat exchanger (40) at the area (L) of lowest air flow.
auxiliary fan” means the fan that ensures air circulation in areas outside the main ventilation circuit of the mine; (ventilateur secondaire)
You may need to track the system that activates a secondary or cooling fan to determine the source of the problem.
Treated effluent is passed out, preferably to a secondary ventilator via a discharge pipe (9).
The air is supplied to the reactor tank via a separate air system (14, 18).
